D. C. BAILEY WINDOW GLASS GUIDE Nov. 10, 1936.

Filed June 14, 1955 :55 in Fig. 7.

Patented Nov. 10, 1936 UNITED STATES lATENT OFFICE 8 Claims.

This invention relates to that class of window glass guides generallyused in automobile bodies, which are so constructed that they may bebent to an extent suilicient to enable them to be conformed to thecurvature of the window frames in which the glass is mounted, an exampleof which is shown in my prior Patent No. 1,963,541 of April 1, 1933.

While the construction of said patent has been extensively employed andis satisfactory in many respects, yet there is a constant demand thatcosts be reduced, and, on account of the fact that some looseness mustbe permitted between the ends of the tongues formed in the sides of thechannel and the edge beads, to permit movement of the tongues thereinwhen the channel is bent, some difficulty has been encountered in massproduction due to the fact that the edge beads sometimes becomedetached.

The objects of my present invention are to provide a construction of thecharacter above referred to, which may be produced at a somewhat reducedcost, as compared with prior constructions of like character and withwhich the mechanical difficulty above referred to may be obviated.

I accomplish these objects by means -of the constructions hereinafterdescribed and illustrated in the accompanying drawing, in which:

. Fig. 1 is a side elevation illustrating a form of my'inventioninstalled in a window frame.

Fig. 2 is a view, partly in cross section and partly in perspective,showing a preferred embodiment of my invention.

: Fig. 3 is a cross sectional view of a slightly members each of whichconsists of a continuous edge portion l2 and a series of suitably spacedtongues I3, which are formed by providing a strip of thin metal ofsuitable width and cutting through the middle portion thereof in thezigrag manner indicated in Fig. 6, so that the strip is cut into twopieces, each of which is then bent to provide a rolled edge portion I4on the continuous portion and a right angularly disposed. lip IS on theend of each tongue, as shown I also provide a base strip [6 of uniformwidth, each edge of which is turned up to provide a narrow flange II, asshown in Fig. 4.. I further provide a base reinforcing strip I8, bothedge portions IQ of which are somewhat off-set, as shown in Fig. 5, andthe :5, distance between the edges thereof being somewhat less than thedistance between the inner sides of the flanges ll.

These parts are then assembled by placing the tongues [3 of the sidemembers against the 10 inner sides of the flanges ll of the base strip16, with the lips 15 engaged with the inner side of the latter andextending inward and then placing the reinforcing strip I 8 on the innerside of the base strip, so that the off-set portions I9 15 thereofextend over the lips l5, and then attaching the strip I8 to the basestrip by spot welding, or other suitable or convenient means, the partsthus being arranged as shown in Fig.

The edge portions of the strips l6 and I8 thus provide continuousgrooves or recesses into which the lips l5 extend, the latter being heldin position therein by the edge flanges I1, and the parts being soarranged that, while there is no substantial looseness between thetongues of the sides and the base sections, yet a slight slidingmovement of the ends of the tongues, 1ongitudinally'of the grooves inwhich they are located, is permitted.

The inner surface of the channel thus formed is lined with suitablecushioning material, which consists of a strip 26, which may beadhesively connected to the base strip I8, and separate side strips 2|,the edges of which are preferably clamped by the rolled-over edges M ofthe sides, as shown in Fig. 2. The outer surface of the sides may bepartly covered by a narrow strip 22 of textile material, which isclamped by the edge l4 and extends for a short distance towards 40 thebottom of the channel, as shown in Fig. 3.

With the above described construction, when the channel, as thus formed,is bent to conform to a curvedwindow frame or casing, as shown in Fig.l, the rolled edges l4 and the base mem- 5 bers l6 and I8 may be bentsufficiently without difiiculty. Bending of the edges 14 will, however,tend to cause the tongues l3 to be swung from their parallel to radialpositions, as shown in Figs.

1 and 10, the lip portions l5 being moved slightly 5 in the groovesformed between the bottom members, so that bending of the sides will bepermitted without strain or buckling. The flanges II on the base section[6 are so narrow that, while they tend to prevent bending of thisportion of the channel, they do not appreciably affect it. As their onlyfunction is to hold the tongues in position in the grooves, the extentto which edge portions are bent to perform this function may be lessthan that indicated in the drawing. The lips [5 also act to hold thesides in upright positions and after the channel is installed and theglass placed in position, the channel will function as efficiently asany other guide used in this relation.

The strip I 8 also reinforces the base strip 16, so that both may beformed from very thin metal and, as there is no waste of metal in theformation of the sides, an actual saving in metal may be made over mysaid prior construction.

In Figs. 8 and 9 two modifications of my invention are illustrated. InFig. 8, a base member 25 is shown the edge portions 26 of which arerolled about reinforcing wires 21, and the side members 28 are providedwith tongues 29, as before described, and the end portions 30 of saidtongues are bent about the exterior of the rolled or beaded edgeportions, so that they are securely held in engagement therewith, butslight-movement of the tongues on the beaded edges of the base member ispermitted when the channel is bent, in substantially the same manner asbefore described in reference to the form shown in Fig. 2. The exteriorof the sides are preferably covered with thin textile material 3|, whichis adhesively secured to the strip of material before it is cut to formthe tongues, as shown in Fig. 6, so that the cloth will be out betweenadjacent tongues and will not interfere with the bending operation. Anarrow textile strip 32 may also be provided on the exterior of thesides similar to the strip 22, in Fig. 3. Cushioning material 33 mayalso be provided on the inner side of the channel similar to that shownin Figs. 2 and 3.

In the form shown in Fig. 9, the base member 34 is somewhat wider thanthe previously described constructions and its edge portions are bentinwardly to form inwardly facing grooves 35. The side members are formedas shown in Fig. '7, but, when placed in position, are placed oppositelyto the position of Fig. 2, so that the lips 36 at their ends extend intothe grooves 35 and are sufliciently loosely engaged therein to permit aslight movement thereof longitudinally of the grooves when the channelis bent. In this instance the base member is shown as covered withtextile material 38 and a portion of the outer sides of the side membersas partly covered by a narrow strip of similar material 31. Cushioningmaterial for the interior of the channel is provided which is similar tothat pre viously described, except that the material 39 on the basemember is extended for the full width of the space between the tongues,to hold the latter in engaged position.

The form of channel shown in Fig. 9 is preferably secured in position bysetting one of the base flanges formed by the reversely bent portions,into a groove at one side of the casing groove and securing a removablemolding over the other base flange.

In both of the last described forms of my invention the action, when thechannel is bent, is precisely the same as that already described inconnection with the form first described, the tongues of the sides beingmoved to slightly radial positions with relation to the curvature of thecasing, when the channel is bent to conform thereto, as shown in Fig.10.

These forms are somewhat advantageous over the first described form inthat less sheet metal is required for their construction.
